Geometry-Aware Diffusion Approximate Posterior Sampling for Sparse-View and Limited-Angle CT

Honglei Brinkmann, Carola-Bibiane Schönlieb, Ander Biguri · 2026

Sparse-view computed tomography (CT) reduces radiation dose and acquisition time and may mitigate motion artifacts. However, angular undersampling provides insufficient information to determine the image uniquely and stably. Limited-angle CT, arising from restricted angular coverage, produces strongly directional infor …

Beyond Unimodal Bases: Pullback Geometry for Multimodal Data

Honglei Brinkmann, Lucas Ng, Georgios Batzolis وآخرون · 2026

Data-driven Riemannian geometry provides nonlinear interpolation and geometric representations of high-dimensional data. For these operations to be statistically meaningful, paths between observations should preferentially traverse high-likelihood regions. Existing scalable pullback constructions typically use a unimod …
